Abstract

A twin-belt casting machine for casting metal strip. The machine is provided with a casting cavity which includes an upstream fixed casting region, in which the belts are in fixed convergent paths in contact with the cast slab, and an adjacent downstream portion in which the belts are adjustable between alignment with the fixed convergent paths and non-alignment therewith (being less convergent or divergent). When the adjustable portions of the paths are moved outwardly relative to the fixed convergent paths, the belts separate from the cast slab at differing predetermined points within the casting cavity. By adjusting the downstream portion of the casting cavity in this manner, the casting machine can operate at essentially constant throughput for a wide range of alloys while ensuring that the cast slab exiting the caster has a temperature within a predetermined range suitable for further rolling to produce sheet product.
